[. . . ] If, after having read it, you decide that you would rather leave installation to a professional, consult your JBL Grand Touring Dealer. Bend up and down repeatedly to break off or use tin snips. · Some Toyota installations may require mounting ears to be removed from opposite sides. [. . . ] However, the use of a small amplifier to attain very high volume levels could lead to overdriving the amplifier. This will generate high distortion levels which can easily damage loudspeakers, even if the rated power of the amplifier is below the rated maximum power handling of the loudspeaker!As a general rule, do not turn up the volume control past the point where you hear distortion in the form of either signal distortion from an overdriven amplifier or mechanical noise from an overstressed speaker. For the best performance and speaker reliability, you should select an amplifier with an output rating slightly higher than the maximum power likely to be used to generate the desired volume levels. This margin of reserve power will ensure that the amplifier will not attempt to deliver more power than its design allows. WARNING: Playing loud music over 120dB can permanently damage your hearing. The maximum volume levels achievable with JBL speakers combined with high power amplification may exceed safe levels for extended listening. When listening at high volume levels, always use hearing protection or turn it down!

Inspect behind panels before you cut or drill. · Make sure that the speaker will physically fit in the mounting location. If door mounting, check for adequate clearance with the window in both closed and open positions as well as for interference with the window crank and power window mechanism. If mounting elsewhere, check for clearance around rear deck torsion bars, glove box or other structural elements. [. . . ] Do not use any cleaners or solvents on the grilles or the speaker drivers.
